There were needless two entries, one for 'newfstatat' and another for
'fstatat', keep just one and pretty print its 'flags' argument using the
fs_at_flags scnprintf that is also used by other FS syscalls such as
'stat', now:
root@number:~# perf trace -e newfstatat --max-events=5

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
